CGT on Main Residence - Renting and No Refurb Paperwork

[trnd777]

Worried about CGT on my main residence - if renting it while overesease and no refurb paperwork.

Spent a good slice of its current value on upgrades and modified layout....had not planned to rent it out.

Owned it 3 years and may rent it out another 3 years.

I actually see a similar post to this just put up.. I only have step-by-step photos and no paperwork as it was just going to be used 3-4 years then sold with no renting..only main residence occupancy.
Things change and then on my main residence will the upgrades sunk in it also attract CGT or can I self-declare/estimate amount put into it when time comes to sell taking into account a portion of time will pull in CGT liability ?

It is your responsibility to self-assess any tax liability. You will only be in trouble if you carelessly or deliberately use an incorrect figure. A justifiable and reasonable estimate is neither.

Great, I also have supporting photographic evidence of extensive upgrades before/after and a building warrant for the 2nd of 2 significant upgrades.

Lesson learned if I move to a new residence - keep every receipt regardless in case things change on who resides there.

I wonder if you use a round figure in both upgrade instances.... if that is not advised ?
